Princess Diana was not murdered by the SAS, police say.
Scotland Yard have written to the Queen and Prince Charles to say there is "no credible or relevant evidence" that members of the elite unit were linked to the car crash in Paris 16 years ago.
In a letter to the Royal Houshold, the coroner and Mohammed Al Fayed, whose son Dodi also died in the crash, Assistant Commissioner Mark Rowley said there were no facts to support rumours of Special Forces involvement after Diana's Mercedes smashed into an underpass pillar.
In August, police were passed material from an SAS sniper, known only as 'Soldier N' via his former parents-in-law.
They said he claimed members of the unit had assassinated the 36-year-old royal seconds after the car crashed.
Detectives took statements, were given access to records and liaised with colleagues in other forces, as well as the Royal Military Police and the Ministry of Defence.
In a copy of the letter passed to Sky News, Mr Rowley wrote: "I am satisfied that there is no evidential basis upon which therefore to reopen any criminal homicide investigation."
Millions of pounds have been spent since the crash by Scotland Yard, French police and an inquest.
Chauffeur Henri Paul's drinking was found to be the cause of the smash, along with the distraction caused by paparazzi.
Scotland Yard say the findings of its inquiry will be released today (17.12.13).
